Oil-sands opponents who have used their public-relations muscle into fighting the Keystone XL pipeline that would flow from Canada into the United States are turning their sights on two pipeline proposals in British Columbia.

Although neither the Trans Mountain nor the Northern Gateway projects cross the border in land, the American arm of the conservation group Forest Ethics said the pipelines will result in an additional 700-plus tankers traversing the waters off the Pacific coast.

“From pipelines to tankers to crude by rail, we’re facing an onslaught of new oil proposals, many of them toxic oil-sands oil, that would turn the Pacific Northwest into a giant shipping lane for oil, gas and for coal,” spokesman Matt Krogh said at a news conference Tuesday in Seattle.
